Glenn Henrich is a multi-instrumentalist who can be heard playing any of his extensive collection of saxes, clarinets, flutes, recorders, keyboards or vibes. His diverse musical interests and styles range from baroque to classical to romantic to modern 'serious' music, and certainly include many varieties of serious (and not so serious) jazz; latin to swing to bebop and beyond.  This Thursday he will continue our obsession with the vibraphones, playing homage to Milt Jackson and the Modern Jazz Quartet - a distinctive contrapuntal bluesy band who brought the vibes to prominence in the 50s and 60s (i don't know whether they'll wear the pin-stripes).
